Application filed August 5, 1910. Serial No. 575,701.

To all whom it may concern:

Be it lrnown that I, NICHOLAS S. Srnn'r, a citizen of the United Statesof America, residing at Neodesha, in the county of Wilson and State ofKansas, have invented new and useful Improvements in Injector-Burners,of which the following is a specification.

This invention relates to improvements in injector burners such as areemployed for injecting a mixture of oil and air into a lirebox, steamconstituting the injecting force as well as the means for atomizing theoil and mixing the latter with air.

One object of the invention is the provision of an injector burner whichis simple and compact in structure embodying comparatively few parts andan arrangement by means of which the injector may be expeditiouslyattached to and detached from the door or other covering of a ire-box.

A further object is the provision of a valve-controlled oil inlet pipeand a valvecontrolled air inlet and a connection between the said valvesserving to open the air inlet valve to admit a quantity of air inproportion to the amount of oil passing through the oil inlet pipe.

lith these and other objects in view, which will more fully hereinafterappear, the present invention consists in certain Vnovel details ofconstruction and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings, and more particularly pointedout in the appended claim; it being understood that various changes inthe form, proportion, size, and minor details of the device may be made,within the scope of the appended claim, without departing from the sirit or sacrificing any of the advantages o the invention.

In the accompanying drawings, forming part of the specification Figure 1is a plan view of the device. Fig. 2 is a longitudinal sectional view onthe line 2 2 of Fig. 1.

Similar numerals of reference are einployed to designate correspondingparts throughout.

rl`he device is shown to include a horizontally disposed mixing chamber,the said mixing chamber being a hollow cylindrical-shaped structure asshown at 5, and having on its upper side and adjacent to one end a flatportion 6. One end portion of the cylinder is provided with an end wall5 and the opposite end is contracted as shown at 8 and formed integralwith the contracted end is an elongated nozzle 10, the bore 11 of whichis in axial alinement with the long axis of the cylinder. The free endof the nozzle 10 is somewhat enlarged to provide a circular head 12 theouter periphery of which is screw-threaded as shown at 13, the said headhaving a flared bore 14 in axial alinement with the threaded bore of thenozzle. The head 18 is to be screwed into the door or other portion of ahre-box, not shown.

By reference now to Figs. 1 and 2 it will be seen that the iiat portion6 is provided with a zone of spaced openings designated by the numeral15. What will subsequently be termed a damper plate is designated by thenumeral 1G. This member is circular in contour and is provided with aplurality of spaced openings 17, and is further centrally provided withan opening to receive a pivot pin 18, the said pivot pin passing throughan opening in the top plate 7, the said opening being equidistant fromthe inner ends of the openings 15. The spaces between the openings inthe flat portion 6 correspond to those between the openings 17 of thedamper 15, so that when the damper is turned to one position theopenings in the flat portion 6 will be bl anlred and when turned toanother posit-ion either the whole or parts of the openings 15 in theflat portion 6 will be exposed.

An oil supply pipe is designated by the numeral 19 and has one endthereof leading through an opening in the top side of the cylinder. Byreference to Figs. 1 and 2 it will be seen that the oil supply pipe, isprovided with a valve casing 20, in which is an ordinary plug valve notshown, the stem 21 of said plug valve extending beyond one side of thecasing and having securely fitted thereto a handle 22. By reference nowto Figs. 1 and 2 it will be seen that rising from the damper plate 16 isan eccentrically disposed stud 23, and extending laterally from the freeend portion of the handle 21 is a stud 24. Connection between the stud2a and stud 23 is established by means of a connectingrod 25, theopposite ends of which are pivoted to the said studs. With thisconstruction it will be manifest when the handle 21 is turned the damperplate 16 will be likewise turned, the relative sizes of the openings inthe valve plug (not shown) and those in the damper plate and top plate 7being such that When the plug Valve is partly open the damper plate willbe turned so as to expose one part of each of the openings 15, theexposed parts of said openings being sulil cient to permit a quantity otair to enter the mixing chamber in proportion to the amount of oilpassing into the mixing chamber through the oil supply pipe 19, theseproportions being sullicient to produce proper combustion When themixture is ignited. By reference nonY to the drawings it Will be seenthat leading into the mixing chamber and at a point adjacent to thecontracted portion S is a steam pipe designated. by the numeral Q6. ltwill be further observed that arranged in the mixing chamber andextending longitudinally or" the same is an axially disposed tube 27,one end of which is termed inte, ral, or otherwise secured to Vthecentral portion of the end plate and the opposite end ot Which extendsto a point adjacent to the nozzle 10. The inner end portion or' thesteam pipe 26 is tapped into or otherwise secured to the tree endportion oit the tube 2T, so that steam passing through the steam pipe 26and outwardly through the tree end of the tube 27, and thence throughthe nozzle l0 will create a partial vacuum in the mixing chamber so thatthe oil and air in the latter will be drawn through the nozzle l0 by thesteam, the latter atomizing the oil in its passage through the nozzle10. lt Will be seen non' by reference to Fig. 2 that arranged in thetube :27 is an auxiliary oil supply pipe Q8, the outer end of said oilpipe being connected nf'ith an oil reservoir (not shown) and the innerend extending a trilie beyond the connection between the tube 27 andsteam pipe 26. This auxiliary oil pipe is to be employed when for anyreason the oil supply pipe 19 becomes inoperative, and it Will beevident when oil flows through the auxiliary supply pipe 28 and steampasses through the steam pipe 26 and nozzle l0 and air is admitted intothe mixing chamber that the oil from the auxiliary supply pipe 28 andair will be drawn through the nozzle l0 by the action of the steam,

From the foregoing, it is evident that I have provided a device which iscomparatively simple in structure and inexpensive in manufacture,embodying few parts and these so arranged that the danger of derangement`will be reduced to a minimum.

l claim :H

An injector burner comprising an enlarged mixing chamber Aterminating atone end in a reduced and elongated nozzle, said mixing chamber having aplurality ot spaced openings in the upper side thereof, an exteriorlydisposed dam por plate rotatably mounted on the mixing chamber andhaving a plurality olE spaced openings to aline with the openings o't`the mixing chamber, a ya ifo-controlled oil inlet pipe leading into themixing chamber, an operating handle connected to said valve, aconnecting rod having its opposite ends connected to the operatinghandle and damper plate, a steam inlet pipe leading into the mixingchamber and having one end secured to that end of the mixing chamberadjacent to the nozzle, a tube arranged in axial alinement with themixing chamber and nozzl e, and having one end extending through the endot' the mixing chamber remote from the nozzle and connected adjacent toits opposite end `with the steam inlet pipe, and an auxiliary oil pipelocated in the tube and extending to a point beyond the connectionbetween the tube and steam inlet pipe.
